我试图读取我用绝对路径提供的文件。当我首先运行我的代码时，我看到的是这条消息：
D:\prog\datascience\anaconda\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
我试过这个：
PATH_TO_FFMPEG = 'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'
pydub.AudioSegment.converter = r'D:\\prog\\ffmpeg-win-2.2.2\\ffmpeg.exe'
我单独安装ffmpeg了pip. 但这没有帮助。当我尝试这个时：
raw_sound = pydub.AudioSegment.from_mp3(file=track_path)
track_path自动生成正确的绝对路径在哪里。所以我得到了这个错误：
